Overview Overview

Sensors in detail

Whether monitoring the speed of a ship‘s engine or railway gearbox, monitoring tempe-

rature of bearings in drive units, recording pressures in hydraulic system or registering

the position of a ship‘s rudder, irrespective of how varied these applications may be they

have three things in common:

In view of their harsh ambient conditions, they place exceptional mechanical and

electrical demands on sensor systems

They are all associated with safety in their respective applications

We offer the right solutions

Sensors for special applicationsDesigners are often faced with the problem of standard sensors not fitting in the con-

cept. This is either due to the mechanical design or the electrical parameters. Such cases

can quickly become complicated and expensive. We have made it our aim to get round

this problem:

The modular design of our sensors enables us to simply turn a standard product into an

affordable, customer-specific product. You specify the requirements and general condi-

tions and together we work out the solution. Just ask us!

NORIS sensors of the futureTo strengthen our market position we continuously strive to expand our product port-

folio by state-of-the-art products that meet market requirements. In the field of sensor

technology we are currently (and will continue in the future) working on:

“Intelligent“ field devices

In future we will develop our tried and tested sensors beyond the task of pure signal

acquisition into “intelligent“ field devices, which can perform simple signal evaluation

tasks and feature corresponding bus connections.

Application-specific combination sensors

It is often necessary to register several measured variables at one point in a machine (es-

pecially in the area of condition monitoring). This is why we will be focussing our efforts

on the development of combination sensors. This will not only reduce the number of re-

quired sensors but also minimise the susceptibility of the entire system to interference,

with the added advantage of reducing the complexity of downstream components.

Applicationsand specialfeatures

Standard applications• Easy to use • Large error tolerance• Large temperature range

Standard and special applications• Can be used at frequencies below

5 Hz• Differential principle:

- Immune to radial toothed wheel vibration (e.g. bearing play,concentricity error)

- Reduction of interference of external magnetic alternating fields (e.g. electric motor magnetic fields)

Special applications• Can be used at frequencies below

5 Hz• Scanning of aluminium, brass and

stainless steel- Reduced weight

• Immune to ferrous metal dust and chips*)- Use in immediate vicinity of brake

dust- Use in “ferrous“ environments- Low maintenance

Today, non-contacting speed sensors are predominantly used to monitor the speed of machines, engines or motors. These sensors

register the rotation of toothed wheels made from ferromagnetic metals such as iron and steel but also aluminium. Depending on

requirements, various measurement principles (see table) can be used (inductive-magnetic principle, difference-hall-effect princip-

le, eddy current principle). So-called impulse bands can also be fitted to enable non-contacting signal acquisition of smooth shafts.

Furthermore, any movement of metal parts or changes in their geometry can be measured with these sensors.

Special applicationsMultichannel sensors

We equip our speed sensors for different

combinations of electrical output signals.

In addition to optimum adaptation of

sensors to a downstream evaluation unit,

this makes it possible to detect direction

of rotation or provide maximum security

by use of redundant signal outputs.

Galvanically isolated parallel output

High temperature applications

For such applications, we offer sensors

that operate based on the inductive-ma-

gnetic measuring principle. These devices

are available with a signal amplifier for a

maximum operating temperature of up

to 160 °C. The special design of the head

unit with integrated insulation element

thermally decouples the electronics of

the signal amplifier from the sensor tip.

This guarantees a long service life even

under difficult thermal conditions. These

devices are available without a signal am-

plifier for a maximum operating tempera-

ture of up to 220 °C.

*) Due to the fact that this measuring principle involves no permanent magnets, the sensor head will not become clogged with metal chips during operation. This reduces the maintenance intervals.

Functional principleThe rotary speed registered by the sensor

is converted by a signal amplifier into an

electrical squarewave signal with a fre-

quency that is directly proportional to

the speed. The signal can be evaluated or

transformed by a downstream signal pro-

cessing component.

Speed sensors

Temperature sensors

Nothing is more varied in the world of sensors than the structural shape. Although there are only a few measuring methods, the

scope of applications and therefore the variety of structural applications are great. Our temperature sensors are specifically designed

for transport technology and shipbuilding. We therefore construct our sensors according to the structural shapes required in these

sectors. In vehicle engineering our sensors are used to monitor bearing temperatures in the underfloor area as well as for engine and

gearbox monitoring. On the other hand, in shipbuilding applications the sensors are used to measure exhaust gas, oil, coolant and be-

aring temperatures. Our product range also includes stern tube sensors. We would be pleased to assist you in selecting which physical

measuring method and which structural shape are best suited for your requirements.

Special designsTemperature sensor with built-in

measuring transducer

Our product range includes temperature

transducers covering the temperature

range from -40 °C to 200 °C. The tem-

perature is registered by a Pt100 sensor

element and converted into analogue,

interference-immune industrial standard

signals (U/I) by an integrated measuring

amplifier directly at the measuring point.

LEDs indicate the operating status of the

measuring transducer.

Signalacquisition

The resistance of NTC thermistors decreases exponentially as tempera-ture increases.

The relationship between tempera-ture and resistance is defined in DIN 43760 – approximately linear measuring range.

The thermocouple (two metals) de-livers a thermoelectric voltage. This measuring method is more intricate than that of NTC or Pt100/Pt1000.

Main propertiesHousing, material and dimensions

When selecting the sensor housing, it is necessary to take into account various require-

ments such as extreme low and high temperatures, condensation, aggressive substan-

ces, oil, corrosion and much more.

Stainless steel (resistant to aggressive substances)

CuNiFer (specially for salt water applications)

Electronics and connection

Cable protection

Our sensors come with different types of

protective cable tubing corresponding to

the required protection class or protec-

tion stipulations (e.g. stone or ice impact

in transport technology) (see page 12/13).

Multichannel sensors

In transport technology, there is an ever

increasing demand for redundant, galva-

nically isolated systems. Our temperature

sensors can therefore be equipped with

two separate Pt100 sensor elements in

one housing.

Customer-specific sensors

Building on various types of sensors as

a basis, it is possible to design effective

customer-specific solutions. By specifying

the material, sensor length, cable length,

connection type and thread, the sensors

are manufactured to suit specific require-

ments.

Protection tubesSensors are often installed together with

protection tubes to make it possible to

replace them during operation (e.g. on

motors). We can supply you with suitab-

le protection tubes in different materials

and dimensions.

Cable harnesses

Customer-specific cable harnesses

On request, we are able to assemble customised cable harnesses to suit your specific

requirements. Several sensors (mostly temperature and/or speed sensors), a plug con-

nector of your choice and protective tubing, if necessary, are combined to make a cable

harness, thus creating a rugged sensor assembly. Our technicians take measurements

on site to ensure optimum adaptation of the cable lengths to the gearbox, engine/mo-

tor, etc.

CablingOur sensors are always equipped with the cable types specified for the vehicle enginee-

ring sector. We apply the following principles to cables in cable harnesses with protec-

tive tubing:

Instead of individual conductors cables are used so that, together with the cable

sheathing, a multi-layered protection system is created, thus effectively avoiding

water ingress as the result of damage to the protective tubing and cable chafing

in the tubing.

All sensor terminals are led directly to the connector to avoid electrical connections

in the protective tubing.

SensorsOur cable harnesses are predominantly connected to speed and/or temperature sen-

sors. The sensors can be combined in any configuration. You will find further informa-

tion on speed and temperature sensors in this brochure or we will gladly provide the

information on request.

Other peripheries are possible and a meeting can be arranged to discuss them in detail.

All our sensors have, of course, been developed in accordance with applicable guide-

lines and are equipped with standard installation flanges as required in the transport

technology applications.

Thanks to the reliability and robustness of our products, for years NORIS has been a leading speed and temperature sensor manufac-

turer in the transport technology sector. A key point for us is to guarantee the effectiveness of our products under extreme conditions.

Great demands are placed on sensors and wiring particularly in the underfloor area. While sensors are mostly installed with mechanical

protection, the cables are often exposed to direct impact of stones and ice and therefore represent a weak point.

For this reason, on customer request, we supply our sensors with protective tubing.

Corrugated tubing for standard applicationsAs common practice in the sector, we

use corrugated tubing for standard ve-

hicle engineering applications to provide

adequate mechanical protection in many

applications. Further advantages include

the low weight and high degree of flexibi-

lity for installation.

Special protective tubingunder extreme conditionsOur years of experience and our close

cooperating with our customers have

proven that corrugated tubing cannot

adequately protect cabling from stone

and ice impact especially on high speed

trains, with soiled track beds and under

extreme temperatures.

Example:

In harsh winters, snow and ice collect on

the corrugated tubing thus drastically in-

creasing the weight. The extremely low

temperatures make the material brittle. Me-

chanical stress such as vibration and shock

can easily cause conventional corrugated

tubing to break.

To protect our products from such extre-

me conditions we have developed a spe-

cial solution, placing us one step ahead of

our competitors:

The advantages of this special tubing can be found not only in the tubing itself but

also in the water and pressure-tight transitions between the tubing and sensors and

connectors. These components must not be subject to torsional stress when installed.

For this reason, all sensors can turn through 360°, thus making our cable harnesses very

easy to install.

Speed pick-ups

Speed pick-ups are used to convert rotary motion into electrically proportional square-wave signals where the drive shaft of the speed

pick-up is mechanically connected directly to the speed source (e.g. motor, generator). Alternatively, a coupling or a flexible shaft can

be used as the connection.

shaft is converted by a Hall switch in the

Pressure transducersP

Pressure transducers register pressures of liquid and gaseous media and convert the

acquired information into linear, proportional, electrical industry standard signals at the

output. The devices are characterised by high degree of reliability, sturdy and compact

design as well as flexibility in adapting to different measurement tasks.

Their applications include the monitoring of:

Lubricating oil and fuel pumps on combustion engines

Hydraulic and pneumatic systems

Filters, compressors, pressure tanks

Fill levels in tank systems

Our pressure transducers are available both as screw-in devices as well as surface-moun-

ted devices with holes for individual piping and are suitable for measuring absolute and

relative pressures (as from -1 bar).

substitute for this component assembly

and offers the following advantages:

Speed pick-ups

Functional principleIn the device, the rotation of the drive

shaft is transferred to a precision poten-

tiometer featuring conductive plastics

technology, which enables virtually infi-

nite resolution over a service life of more

than 10 million shaft rotations. The drive

shaft turning through the specified angle

range initiates an analogue change in the

resistance by the specified ohmic value.

These potentiometers are designed as

2-stage or 3-stage units to enable signal

evaluation in redundant or galvanically

isolated systems. The connections of each

potentiometer stage are led outwards for

external wiring.

Our rotation angle pick-ups are used wherever angular positions need to be registered reliably and converted into electrical signals

by control systems for status monitoring purposes. The sensors are used, for example, in systems for displaying actual values and limit

thresholds. As angle of rotation sensors are mostly installed directly on the bearing-mounted shafts of the objects to be measured and

are therefore often difficult to access in such system, we attach particular importance to ensuring our sensors are durable, provide a

long service life and are maintenance-free.

Tachogenerators

Our AC tachogenerators are predomi-

nantly used wherever operation of indi-

cator and display devices independent

of mains power supply is required. These

maintenance-free devices are built to be

extremely robust, making them ideal for

harsh operating conditions. They can be

driven either with couplings directly at

the rotor shaft or indirectly via friction

wheels, belt pulleys, sprockets or flexible

shafts.

Functional principleTachogenerators operate in accordance

with the generator or exciter principle si-

milar to a bicycle dynamo: A permanent

magnet rotates in a fixed winding where

it induces an AC voltage signal that is pro-

portional to the speed of the drive shaft.

This voltage and/or its frequency can be

used as measuring variables.

Multiphase AC voltage tachogenerators

Multiphase AC tachogenerators supply

two identical, galvanically isolated sinu-

soidal signals that are electrically offset by

90° with respect to each other. This makes

it possible for a downstream evaluation

unit to determine direction of rotation.

Tachogenerators with integrated

directional rotation recognition. Depen-

ding on the type of device, direction of

SIGNAL PROCESSING

19


Measuring transducers and limit value switches are often used to realise simple monitoring tasks. They provide galvanic isolation,

signal conversion and conditioning. They are used wherever the most demanding requirements are made in terms of reliability and

long service life. The compact devices can be installed both in central control cabinets as well as directly in the vicinity of motors. As

our measuring transducers and limit value switches are often used together they are housed in a single plastic enclosure. The inputs

of our devices are perfectly adapted to our sensors.

Measuring transducersMeasuring transducers convert measured electrical input variables (mainly sensor sig-

nals) into standardised output signals proportional to the sensor signal or corresponding

field bus protocols. Measuring transducers can be used, for example, to adapt sensors to

downstream controllers, achieve galvanic isolation and transfer weak, susceptible sen-

sor signals over longer distances.

Special designs for special applicationsWe develop devices with special functions for special applications such as a measuring

transducer with integrated error correction for railway wheel wear. The device is sui-

table for all commonly used wheel diameters. The drum scale for setting the limit is

protected by a sealed cover.

Limit value switchesLimit value switches are used for the purpose of monitoring measured variables. The

built-in relay (changeover contact) switches when the actual value of the measured

signal reaches the set threshold. In this way statuses can be monitored by downstream

evaluation electronics or switching operation can be implemented directly.

Special designs for special applicationsWe develop devices with special functions for special applications such as a limit

value switch with test function: A higher measuring signal is simulated by pressing an

integrated button for the purpose of testing the monitoring system without having to

operate the system in the critical range.

Parametrisation

The switching thresholds are set mechanically by means of a drum scale (potentiomet-

ric). A sealed cover is available to prevent the setting being changed inadvertently or by

unauthorised persons.

Our multifunctional devices are a combination of measuring transducers and switch-

gear. They are used wherever several variables are to be monitored with one device,

special measurements such as slip and offset measurement are performed and flexible

parametrisation is required.

Solution-orientated multifunctional devicesOur multifunctional devices are based on solution-orientated design. Recurring appli-

cations that to date had to be realised by several individual components are now per-

formed by one single device. To this end we equip such devices with functions that you

require for your specific applications.

The benefits for you are:

Optimum price/performance ratio by adapting the scope of electronics, interfaces

and functions to specific application requirements

Error minimisation in installation and servicing

Menu-controlled parametrisation for maximum ease of operation

Special features Wire break detection (speed sensors)

Speed evaluation with “NORISPEED“NORISPEED is an evaluation unit for con-

nection of up to two speed sensors. The

properties of a measuring transducer and

of a limit value switch are combined and

evaluations based on the acquired mea-

sured data are made available via swit-

ched outputs or standard signal outputs.

The user can set up the device directly

with the aid of menu-controlled navigati-

on and an integrated LC display. Current

measured values can be shown on the

display, making them easy to check.

Applications Speed measurement and conversion

to standard signals

Directional rotation recognition in

reversing gearbox systems

Speed monitoring or engine protec-

tion (nominal speed and overspeed

detection or drive shutdown with

signalling to a remote station,

e.g. to a safety system)

Gearbox monitoring by means of slip

measurement

Application examplesSpeed measurement

Two independent speeds (up to 10,000

rpm) can be registered and converted

into proportional analogue signals. The

digital outputs can be individually desi-

gnated to the two frequency inputs and

assigned different functions (e.g. limit

monitoring).

Directional rotation recognition

The signals of two radially offset speed

sensors or those of a dual sensor are

evaluated in the device and sent to two

digital outputs. All analogue and digital

outputs are freely programmable in this

mode.

Slip measurement

Two speeds are measured and evaluated

with mechanical, parametrisable refe-

rence to each other. The freely program-

mable outputs can forward the speed

signals to a downstream evaluation unit.

The digital outputs can be used for status

messages and limit monitoring purposes.

Offset measurement

Offset measurement refers the measured

speed to a set target speed and the result

is output as an analogue value (via ana-

logue outputs), e.g. to precisely monitor

the target speed of a generator. The sca-

ling of the speed deviation is freely pro-

grammable. The digital outputs can be

used for status messages and limit moni-

toring purposes.

Measured value conversion

The frequency signal can be converted

into standard signals (see table). In con-

nection with directional rotation reco-

gnition, the signal range can be split for

anticlockwise and clockwise rotation.

Display solutionsas part of automation and safety engineering

Whether on the bridge of a luxury yacht, river boat or of an oil tanker; whether on open

deck or in the engine control room; whether in control panels or directly in the vicinity

of engines; whether speed, rudder position, propeller pitch, temperature, pressure or

wind direction; whether in shipbuilding, transport technology or industry; whether in

Europe, Asia or America: Our indicators are used in a vast number of varied applications

throughout the world. This is thanks to the robust design and reliability of our products

as well as their adaptability to any application.

Indicators for special applicationsThe modular design of our indicators allows us to easily customise special solutions.

This requires a well-conceived housing design in standard sizes and a controller-based

stepping-motor and lighting concept. You can choose from a large selection of standard

scales. On request we will adapt the scales to your specific application or design them

to your specifications.

NORIS visualisation in the future

Our aim is to offer technical progress of the highest quality at an attractive price also in

the future. To this end we are focussing on:

“Intelligent“ indicators

Today‘s indicators have to do more than simply display measured data. By combining

the indicator function with other functions such as those of a measuring transducer

and/or limit value switch, the number of components as well as system costs can be

greatly reduced. We are developing new solutions in this field.

GUI (Graphical User Interfaces)

The visualisation of measured data with graphical user interfaces will soon be common

place in many applications. We are developing customised products in this field. The

advantages of devices with this technology include:

Adaptation of the GUI to measured variables, scales, colours, configuration and

parametrisation for maximum flexibility

Display of additional important information for the user

Integrated control functions are possible

Analogue indicators

Our analogue indicators feature step-

ping-motor technology or are equipped

with a moving-coil element. They are pri-

marily used wherever great demands are

placed on durability and reliability. They

are largely unaffected by harsh ambient

conditions and thermal extremes.

Long lifetime and easy readable values

even in case of direct sunlight are further

advantages compared to indicators with

displays.

Functional principle and design of the stepping-motor indicator - NORIMETER Our analogue indicators with integrated stepper motor technology are reliable over a long service life. Measured values are digitised

by an A/D converter and shown by means of a processor-controlled, high resolution stepper motor with illuminated plastic pointer on

an individually configurable scale. The combination of high quality components and materials with a sophisticated software system

ensures maximum accuracy and flexibility. The high EMC protection class as well as the immunity to shock and vibration as stipulated

by transport technology and most ship classification bodies enable continuous operation under increased mechanical stress condi-

tions such as direct installation on a motor/engine.

Lighting

Innovative LED lighting concept for

bright, uniform scale and optional

pointer lighting

The basic brightness setting (pointer

and scale separate) can be adapted to

adjacent devices and ambient condi-

tions

360° indicatorsOur 360° indicators that are used in con-

nection with azipods are equipped with

dials instead of pointers. The indicator or

dial performs automatic travel optimisa-

tion.

MED (Marine Equipment Directive)An MED certificate (European Marine

Equipment Directive) is generally requi-

red for use of indicators for ship naviga-

tion (propeller pitch, speed, rudder po-

sition). For this reason, our NORIMETER

stepping-motor indicators have been ap-

proved together with our DWA series ro-

tation angle pick-ups and measuring am-

plifiers as a complete measuring chain in

order to comply will all necessary criteria.

“Intelligent“ indicatorsIn addition to simply showing measured

values, for us the term “intelligent“ indica-

tor means providing extended functions,

which enable the indicator to convert

measured values or evaluate signals. The-

se devices were developed as a solution

to specific problems, thus avoiding unne-

cessary costs.

NORIMETER 3 - Indicator with integrated

directional rotation detection

Two speed sensors or a dual sensor (two

sensors in one enclosure) can be con-

nected to this device without the need

for additional electronics. The indicator

identifies the direction of rotation based

on the phase angle of both sensor signals

and shows it together with the speed on

the scale (right/left stop).

Special solutions

Our indicators can of course be adapted

to specific customer requirements.

You have the choice to:

Select the colour of the scale dial from

a range of colours

Define the colour of the scale

Select the colour of the scale and

pointer lighting

Have customised scale and zero point

calibration

More extensive changes are also possible.

At various points we have already prepa-

red appropriate concepts in advance and

hope we have sparked an interest.

Input and output expansions

Scales and pointersThe “face“ of any indicator is its scale. This

feature gives every indicator its individual

character and personal touch. We have

available a large selection of standard

scales or if necessary we can also create

special scales that precisely conform to

your specific requirements - simply talk

to us.

If not otherwise specified, the scale la-

belling and graduation will conform to

DIN 43802 and DIN 43780.
